This study evaluates the clinical/immunological features and outcomes of 91 patients with the diagnosis of transient hypogammaglobulinemia of infancy(THI). Mean age at diagnosis was 8.4±5.2 months. IgG levels normalized at 30.6±11.88 months. Sixty three patients (69.3%) resolved in their first 3 years of life and 28 patients (30.7%) thereafter. In the univariate analysis, presence of atopy, occ...

objective: morphological changes of ca1 neurons in rat hippocampus after transient and permanent focal cerebral ischemia were studied to clarify the nature of postischemic cell death in the subfield. materials and methods: male adult rats were divided into 3 groups: control (shamoperated), transient ischemic group (30 minutes of mcao followed by 48 hours of reperfusion), and permanent ischemic ...

In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...

In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...

Transient global amnesia (TGA) is a disorder characterized by a sudden attack of severe anterograde amnesia, where patients are unable to learn and recall novel information during the event. Although fi rst described at least 60 years ago, the etiology and pathophysiology of TGA remain unclear and have been a matter of debate among clinicians and researchers. In this paper, we present a case of...

This paper deals with a numerical and experimental study of ultrasound induced cavitation. On the basis of a computational analysis of Gilmore’s equation for the individual bubble dynamics, a slight decrease in the pressure radiated by a single bubble immediately before reaching the transient cavitation regime is predicted. Experiments presented in this paper confirm this observation. Therefore...

Background: The transient tachypnea is a common respiratory problem in the neonate. One of the significant issues in pathophysiology of this disorder is the delayed reabsorption of the fluid by the neonate’s lungs and the effusion of fluid in the lungs. The purpose of this study is to evaluate the effects of restrictive fluid management in transient tachypnea of the neonate. Methods: The presen...

In the conversion of fuel in the Tehran Research Reactor core from Highly- Enriched Uraniutn to Low-Enriched Uranium fuel neutronics analysis, thermal hydraulic calculations and kinetic performance of the core have to be studied. In this study, static and dynamic core performance for HEU and LEU fuels were investigated. In static conditions, two groups of neutron flux distributions in axia...

this paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (srm) during offline and standstill modes. in this method, the fault signature is differential induced voltage (div) achieved by injecting diagnostic pulses to the motor windings. it will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...
